Many Respiratory disorders, such as chronic obstructive pulmonary disease, asthma, and pneumonia, all have clinical and therapeutic involvement of the oral cavity, emphasising the need for routine dental examination and close inspection of the oral cavity, as well as active cooperation between dentists and pulmonologists.


To find the prevalence of oral manifestations of hospitalised patients with respiratory diseases.

Patients and Methods

This cross-sectional study was conducted from October 2019 to March 2020 in an internal medical teaching hospital in Sualimani-Iraq, which included one hundred patients admitted and diagnosed with respiratory diseases. Patients were interviewed regarding oral manifestations of respiratory diseases, and they were subjected to complete oral mucosal examination. In addition, required data were collected through a specially designed questionnaire.


Females were predominant (55%) with a mean age (64.00 ± 14.08) years old. The age groups (51-60) and (61-70) among COPD and Asthmatic patients were more affected by respiratory diseases, with significant sex differences being more in females. (P ˂ 0.001). The most frequent oral manifestation was oral candidiasis (35%), mainly on the palate, mostly in asthmatic and COPD patients. Oral ulceration (12%) primarily on lower labial mucosa and tongue was statistically significant (P ˂0.001) than other sites. Other reported manifestations were gingival enlargement (49%), coated tongue (10 %), geographic tongue (4%), fissured tongue (6%), hairy tongue (3%). The predominant subjective symptom was the feeling of dry mouth (89%); most of the patients (49%) had adequate oral hygiene. 


females and asthma were more reported in hospitalized respiratory diseased patients. Oral candidiasis predominantly on the palate and dry mouth (xerostomia) was the predominant patients’ symptom.
